What Is A Socket Error


All sockets are created with an associated address family (that is, AF_INET for Internet protocols) and a generic protocol type (that is, SOCK_STREAM). You’ll be auto redirected in 1 second. If we add the same error checking code we get this; if(bind(Socket,(SOCKADDR*)(&serverInf),sizeof(serverInf))==SOCKET_ERROR) { int nError=WSAGetLastError(); std::cout<<"Unable to bind socket: "<Source

Do not set non-zero timeout on non-blocking sockets to avoid this ambiguity (see Chapter 9 for more information). Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), See also: WSAHOST_NOT_FOUND, WSANO_DATA, WSATRY_AGAIN WSASYSNOTREADY (10091) Network subsystem is unavailable Berkeley description: No equivalent. For example, a socket call requests a SOCK_DGRAM socket, but specifies a stream protocol. 10044WSAESOCKTNOSUPPORTSocket type not supported. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

What Is A Socket Error

In most cases, the default Winsock that comes with your OS is appropriate. You could also try to resolve another hostname you know should work, to check that the name resolution server application is running. A socket operation was attempted to an unreachable network.

  1. WSAEISCONN (10056) Socket is already connected.
  2. WSAEHOSTUNREACH 10065 No route to host.
  3. WSAELOOP 10062 Too many levels of symbolic links.
  4. The WSAEAFNOSUPPORT is the likely substitute error for this in WinSock, although its Berkeley meaning is slightly different.

WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: Any function that does network I/O: recv(), recvfrom(), send(), FD_READ, FD_WRITE See also: WSAEHOSTUNREACH WSAENOBUFS (10055) No buffer space available. Berkeley description: A connect or send request failed because the connected party did not properly respond after a period of time. (The timeout period is dependent on the communication protocol.) WinSock But that's not to say you shouldn't still be prepared. Socket Error 11004 User suggestions: This error indicates a shortage of resources on your system.

WinSock description: Similar to Berkeley. Socket Error Codes Linux User suggestions: Some network systems have commands to report statistics. recv() & recvfrom(): socket not bound (for Dgram) or not yet connected (for Stream), or the requested length is zero (whether a length >32K is acceptable as a non-negative value is Note: Although connect() and FD_CONNECT also have this error listed, the documentation specifically states that WSAEADDRNOTAVAIL is appropriate if INADDR_ANY is passed as a destination address.

This may indicate the file was deleted on the NFS server or some other catastrophic event occurred. Windows Socket Error Windows 10 email etiquette adding people to the thread vs reaching out directly We don't support this API version. Developer suggestions: Chances are, that if you encounter this error, your application ignored the failure of some previous function. In it's place, WinSock uses the error WSAENETUNREACH, exclusively.

Socket Error Codes Linux

WSAESHUTDOWN 10058 Cannot send after socket shutdown. great post to read Berkeley description: The support for the socket type has not been configured into the system or no implementation for it exists. What Is A Socket Error Although the specification doesn't list an error for a function, it does allow for it. Socket Error 10054 Connection Reset By Peer An application attempts to use an event object, but the specified handle is not valid.

A service provider returned a bogus procedure table to Ws32.dll. (Usually caused by if one or more of the function pointers is null.) OS dependentWSAINVALIDPROVIDERInvalid service provider version number. http://discusswire.com/socket-error/socket-error-10022.html There is another possibility: you are accessing a socket which the current active task does not own (that is, you're trying to share a socket between tasks). For example, you cannot use the ARPA Internet UDP protocol with type SOCK_STREAM. The only function that takes these two explicit parameters is socket.WSAENOPROTOOPT (10042) Bad protocol option A bad option or level was specified in a getsockopt(2) or setsockopt(2) call. Winsock Error 10053

If there is more than one Winsock DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. Winsock only allows a single blocking operation to be outstanding per task (or thread), and if you make any other function call (whether or not it references that or any other WinSock functions: getpeername(), recv(), recvfrom(), send(), sendto(), setsockopt(), shutdown(), FD_CONNECT See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAENOTEMPTY (10066) Directory not empty. have a peek here WSAELOOP (10062) Too many levels of symbolic links A pathname lookup involved more than eight symbolic links. (Too many links were encountered in translating a pathname.)WSAENAMETOOLONG (10063) File name too long

WSAEBADF 10009 Bad file number. Socket Error 10061 Connection Refused The application has tried to determine the status of an overlapped operation, which is not yet completed. They signal unusual error conditions for which there's no WinSock error equivalent.

Do you have the Winsock DLL that supports the version of the Winsock specification required by the application?

You cant have two servers using the same port number, as we have just found out! Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions. If it does respond, then this problem might have been a transient one (so you can reconnect now), or the server application you were connected to might have terminated (so you Winsock Error 10054 Fix Probability of throwing a die Does a long flight on a jet provide a headstart to altitude acclimatisation?

WinSock description: Same as Berkeley; the option is unknown or unsupported. If so, then the application might have had a problem resolving the name. OS dependentWSA_INVALID_PARAMETEROne or more parameters are invalid. Check This Out WSASYSNOTREADY (10091) Network SubSystem is unavailable The Winsock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable.

WSAEPROTONOSUPPORT 10043 Protocol not supported. For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency.

If you used a hostname, did it resolve to the correct address? An existing connection was forcibly closed by the remote host. Berkeley description: An operation on a socket or pipe was not performed because the system lacked sufficient buffer space or because a queue was full. The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time.

WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), See also: WSAHOST_NOT_FOUND, WSANO_RECOVERY, WSATRY_AGAIN WSANO_RECOVERY (11003) This is a non-recoverable error Berkeley description: This is a The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. Berkeley description: The protocol has not been configured into the system, or no implementation for it exists. Instead, let the network system assign the local port (very few application protocols require a client to bind to a specific port number or port number range).
